Note!
During the safe cascading of a drive system, the SS1 mode (C15306) (from
V1.3) must be parameterised to "STO after stopping time". The first one of the
drives which is at standstill changes to the STO status, thereby triggering STO
for the entire drive system. Those drives which are not at standstill yet are
coasting in an uncontrolled way. Therefore, a fixed stopping time for all drives
makes sense here.
